Microsoft releases Windows 10 Insider Preview build 10576 for PCs with a range of new features

Microsoft's Gabe Aul said this week that the company was "working on something we've never done before" for the release of its latest Windows 10 preview builds. Today, he revealed the surprise: new builds for Mobile and PC on the same day.

Earlier today, the company rolled out its latest Windows 10 Mobile Insider Preview, build 10581, and now, it's also released build 10576 for PCs to Insiders on the Fast ring.

"Not only does this build have a good set of bug fixes and fit-and-finish," Gabe said today in a post on the Windows Blog, "it also includes a few new things for you to try", as he went on to explain:

Media Casting in Microsoft Edge: You can now use Microsoft Edge to cast video, picture, and audio content from your browser to any Miracast and DLNA enabled device on your network.

We’ve got a few scenarios for you to try out:

Cast a video from YouTube: Go to YouTube.com in Microsoft Edge. Click on the “…” menu and the top left, and select “Cast media to device” and select the Miracast or DLNA device you want to cast to.

Cast a Facebook photo album: Login to Facebook in Microsoft Edge and click on the first photo in one of your photo albums to cast. Click on the “…” menu and the top left, and select “Cast media to device” and select the Miracast or DLNA device you want to cast to. Navigate through your photo album by clicking on the forward and backward buttons.

Cast your music from Pandora: Login to Pandora in Microsoft Edge to get to your music and click on the “…” menu and the top left, and select “Cast media to device” and select the Miracast or DLNA device you want to cast to.

Try this feature out and let us know what you think.

Please note: Casting protected content (content from places like Netflix and Hulu) is not supported.

Ask Cortana inside PDFs in Microsoft Edge: You can now highlight text while reading a PDF in Microsoft Edge and right-click to “Ask Cortana” to find additional information.

Updated Xbox beta app for Windows 10: The Xbox beta app for Windows 10 was updated last Friday which includes the ability to easily find and add Facebook friends who are also on Xbox Live to play, chat, and share clips – a top requested feature. In addition to that new feature, voiceover recording functionality has been added to Game DVR, and the Store in the Xbox beta app will allow you to search for and purchase Xbox One games – including Games with Gold and Deals with Gold promotions, and Xbox One 25-digit codes will be redeemable within the app. For more information on this update – check out this post on Xbox Wire.

By the way, it's worth mentioning that WinBeta's Zac Bowden has pointed out that the screen casting feature - which Microsoft says is new in build 10576 - was actually present in the last preview, build 10565.
